| prevalence of infection with rickettsia helvetica in ixodes ricinus ticks feeding on non-rickettsiemic rodent hosts in sylvatic habitats of west-central poland. | ixodes ricinus is the most prevalent and widely distributed tick species in european countries and plays a principal role in transmission of a wide range of microbial pathogens. it is also a main vector and reservoir of rickettsia spp. of the spotted fever group with the infection level ranging in poland from 1.3% to 11.4%. nevertheless, little research has been conducted so far to identify reservoir hosts for these pathogens. a survey was undertaken to investigate the presence of rickettsia spp ... | 2016 | 26515058 |
| environmental conditions in favour of a hantavirus outbreak in 2015 in germany? | bank voles can harbour puumala virus (puuv) and vole populations usually peak in years after beech mast. a beech mast occurred in 2014 and a predictive model indicates high vole abundance in 2015. this pattern is similar to the years 2009/2011 when beech mast occurred, bank voles multiplied and human puuv infections increased a year later. given similar environmental conditions in 2014/2015, increased risk of human puuv infections in 2015 is likely. risk management measures are recommended. | 2016 | 26177110 |
| reservoir-driven heterogeneous distribution of recorded human puumala virus cases in south-west germany. | endemic regions for puumala virus (puuv) are located in the most affected federal state baden-wuerttemberg, south-west germany, where high numbers of notified human hantavirus disease cases have been occurring for a long time. the distribution of human cases in baden-wuerttemberg is, however, heterogeneous, with a high number of cases recorded during 2012 in four districts (h districts) but a low number or even no cases recorded in four other districts (l districts). bank vole monitoring during ... | 2016 | 27918151 |
| [variants of the immunoreactivity and infectious process in bank vole (myodes glareolus) experimentally infected with the hantavirus puumala (puuv)]. | as a result of a longitudinal study of the puumala hantavirus (puuv) in the experimentally infected bank voles (myodes glareolus), we revealed three groups of the voles differing in the immunoreactivity and viral antigen concentration in the organs. the close correlation between these parameters suggested the existence of various mechanisms of the hantavirus persistence in the host. | 2016 | 25549467 |
| declining ecosystem health and the dilution effect. | the "dilution effect" implies that where species vary in susceptibility to infection by a pathogen, higher diversity often leads to lower infection prevalence in hosts. for directly transmitted pathogens, non-host species may "dilute" infection directly (1) and indirectly (2). competitors and predators may (1) alter host behavior to reduce pathogen transmission or (2) reduce host density. in a well-studied system, we tested the dilution of the zoonotic puumala hantavirus (puuv) in bank voles (my ... | 2016 | 27499001 |
| regional differences in long-term cycles and seasonality of puumala virus infections, finland, 1995-2014. | puumala hantavirus (puuv) causes haemorrhagic fever with renal syndrome in humans, an endemic disease in finland. we aimed to study recent trends in puuv infections in finland, to evaluate whether there are regional differences in seasonality and long-term cycles and whether the patterns have changed over time. we analysed serologically confirmed acute puuv infections reported to the national infectious disease register from 1 april 1995 to 31 march 2014. a total of 30 942 cases of puuv infectio ... | 2016 | 27113030 |
| characterization of puumala hantavirus in bank voles from two regions in the netherlands where human cases occurred. | puumala hantavirus (puuv) is the most common and widespread hantavirus in europe and is associated with a mild form of haemorrhagic fever with renal syndrome in humans, called nephropathia epidemica. this study presents the molecular characterization of puuv circulating in bank voles in two regions of the netherlands. most human cases of hantavirus infection are from these two regions. phylogenetic analysis of the (partial) s, m and l-segments indicated that the dutch strains belong to the ce li ... | 2016 | 27075118 |

| spatial and temporal epidemiology of nephropathia epidemica incidence and hantavirus seroprevalence in rodent hosts: identification of the main environmental factors in europe. | in europe, the increasing number of nephropathia epidemica (ne) infections in humans, caused by puumala virus carried by bank voles (myodes glareolus), has triggered studies of environmental factors driving these infections. ne infections have been shown to occur in specific geographical areas characterized by environmental factors that influence the distribution and dynamics of host populations and virus persistence in the soil. here, we review the influence of environmental conditions (includi ... | 2016 | 26996739 |
| temporal dynamics of puumala hantavirus infection in cyclic populations of bank voles. | understanding the dynamics of zoonotic pathogens in their reservoir host populations is a prerequisite for predicting and preventing human disease epidemics. the human infection risk of puumala hantavirus (puuv) is highest in northern europe, where populations of the rodent host (bank vole, myodes glareolus) undergo cyclic fluctuations. we conducted a 7-year capture-mark-recapture study to monitor seasonal and multiannual patterns of the puuv infection rate in bank vole populations exhibiting a ... | 2016 | 26887639 |
| selective predation on hantavirus-infected voles by owls and confounding effects from landscape properties. | it has been suggested that predators may protect human health through reducing disease-host densities or selectively preying on infected individuals from the population. however, this has not been tested empirically. we hypothesized that tengmalm's owl (aegolius funereus) selectively preys on hantavirus-infected individuals of its staple prey, the bank vole (myodes glareolus). bank voles are hosts of puumala hantavirus, which causes a form of hemorrhagic fever in humans. selective predation by o ... | 2016 | 26873607 |
| detection of puumala virus in the tissue of infected naturally rodent hosts in the area of central dinarides. | hantaviruses are the causative agents of haemorrhagic fever with renal syndrome (hfrs) in euroasia and of hantavirus cardiopulmonary syndrome (hcps) in the north, central and south america. hfrs is endemic in the balkan peninsula, where sporadic cases or outbreaks have been reported. puumala virus (puuv) is the causative agent of nephropathia epidemica (ne), a mild form of hfrs. puuv is carried by the bank voles (myodes glareolus). in this study, we investigated viral rna from 76 tissues samples ... | 2016 | 26800777 |
| serological survey in the finnish human population implies human-to-human transmission of ljungan virus or antigenically related viruses. | ljungan virus (lv) is a picornavirus related to human parechoviruses (hpev). the virus has been found in bank voles (myodes glareolus) and several other rodent species, and suggested to have zoonotic potential. thus far, seroepidemiological data on lv infections in humans are scarce. in this study, we aimed to characterize the demographic and geographical distribution of lv-reactive antibodies in finland, and to investigate its occurrence in patients suspected of having a rodent-borne disease, n ... | 2016 | 26489898 |
| n-terminal prion protein peptides (prp(120-144)) form parallel in-register β-sheets via multiple nucleation-dependent pathways. | the prion diseases are a family of fatal neurodegenerative diseases associated with the misfolding and accumulation of normal prion protein (prpc) into its pathogenic scrapie form (prpsc). understanding the fundamentals of prion protein aggregation and the molecular architecture of prpsc is key to unraveling the pathology of prion diseases. our work investigates the early-stage aggregation of three prion protein peptides, corresponding to residues 120-144 of human (hu), bank vole (bv), and syria ... | 2016 | 27576687 |
| seed preferences by rodents in the agri-environment and implications for biological weed control. | post-dispersal seed predation and endozoochorous seed dispersal are two antagonistic processes in relation to plant recruitment, but rely on similar preconditions such as feeding behavior of seed consumers and seed traits. in agricultural landscapes, rodents are considered important seed predators, thereby potentially providing regulating ecosystem services in terms of biological weed control. however, their potential to disperse seeds endozoochorously is largely unknown. we exposed seeds of ara ... | 2016 | 27547355 |
| de novo lipogenesis is suppressed during fasting but upregulated at population decline in cyclic voles. | arvicolines are susceptible to the development of fatty liver during short-term fasting. we examined the potential role of de novo lipogenesis (dnl) (i) in the development of fasting-induced fatty liver and (ii) during a population cycle by measuring the mrna expression of acetyl-coa carboxylase-1 (acc1) and fatty acid synthase (fas). laboratory voles (microtus oeconomus and microtus arvalis) were fed or fasted for 12 or 18 h and their liver mrna levels were determined. both species showed decre ... | 2016 | 26892709 |
| discovery of novel alphacoronaviruses in european rodents and shrews. | eight hundred and thirteen european rodents and shrews encompassing seven different species were screened for alphacoronaviruses using pcr detection. novel alphacoronaviruses were detected in the species rattus norvegicus, microtus agrestis, sorex araneus and myodes glareolus. these, together with the recently described lucheng virus found in china, form a distinct rodent/shrew-specific clade within the coronavirus phylogeny. across a highly conserved region of the viral polymerase gene, the new ... | 2016 | 27102167 |
| [functional features of microbial communities in the digestive tract of field voles (microtus rossiaemeridionalis and clethrionomys glareolus)]. | the nitrogen-fixating and cellobiohydrolase activity, the nitrogen (n) and carbon (c) contents, and the number of microorganisms in the prestomach, cecum, and colon of two vole species were studied: the southern vole (microtus rossiaemeridionalis) and the bank vole (clethrionomys glareolus), which is characterized by a mixed type of diet. the nitrogen-fixating activity in the cecum was found to be the highest in the voles compared with the mammals studied earlier. the seasonal dynamics of both n ... | 2016 | 22988758 |
| genetic variations of turkish bank vole, myodes glareolus (mammalia: rodentia) inferred from mtdna. | the bank vole, myodes glareolus, lives in deciduous forests throughout the palearctic region. in turkey, this species is distributed only in northern anatolia (the black sea region) where these forests exist. this study reveals genetic differentiation among bank vole populations based on two regions of mitochondrial dna (cytochrome b and d-loop). populations in northern anatolia are divided into two genetic lineages (the "eastern" and "western black sea" lineages) by the kızılırmak valley. while ... | 2016 | 26540489 |
| [embryonic malformations in rodents in forest communities of the bryansk region exposed to radioactive pollution]. | embryonic malformations have been described and classified in small forest rodents (microtus oeconomus, clethrionomys glareolus), which had several generations living on the radioactively contaminated territory and were exposed to small doses of radiation (140-200 mkr/h). | 2016 | 9467640 |
| transmissibility of gerstmann-sträussler-scheinker syndrome in rodent models: new insights into the molecular underpinnings of prion infectivity. | prion diseases, or transmissible spongiform encephalopathies, have revealed the bewildering phenomenon of transmissibility in neurodegenerative diseases. hence, the experimental transmissibility of prion-like neurodegenerative diseases via template directed misfolding has become the focus of intense research. gerstmann-sträussler-scheinker disease (gss) is an inherited prion disease associated with mutations in the prion protein gene. however, with the exception of a few gss cases with p102l mut ... | 2016 | 27892798 |
| isolation of a defective prion mutant from natural scrapie. | it is widely known that prion strains can mutate in response to modification of the replication environment and we have recently reported that prion mutations can occur in vitro during amplification of vole-adapted prions by protein misfolding cyclic amplification on bank vole substrate (bvpmca). here we exploited the high efficiency of prion replication by bvpmca to study the in vitro propagation of natural scrapie isolates. although in vitro vole-adapted prpsc conformers were usually similar t ... | 2016 | 27880822 |
| prpc governs susceptibility to prion strains in bank vole, while other host factors modulate strain features. | bank vole is a rodent species that shows differential susceptibility to the experimental transmission of different prion strains. in this work, the transmission features of a panel of diverse prions with distinct origins were assayed both in bank vole expressing methionine at codon 109 (bv109m) and in transgenic mice expressing physiological levels of bank vole prpc (the bvprp-tg407 mouse line). this work is the first systematic comparison of the transmission features of a collection of prion is ... | 2016 | 27654300 |
| modification of nickel accumulation in the tissues of the bank vole myodes glareolus by chemical and environmental factors. | in a full factorial laboratory experiment, the effects of temperature and two chemical stressors (nickel and chlorpyrifos) on the accumulation of nickel in the liver and kidney of bank voles were studied. the nine-week experiment consisted of three periods: acclimatisation (3 days), intoxication (6 weeks) and elimination (3 weeks). during the main intoxication phase the animals were orally exposed for 42 days to different doses of nickel (ni) (0, 300 and 800mg/kg food) or chlorpyrifos (cpf) (0, ... | 2016 | 27632790 |

| genomic response to selection for predatory behavior in a mammalian model of adaptive radiation. | if genetic architectures of various quantitative traits are similar, as studies on model organisms suggest, comparable selection pressures should produce similar molecular patterns for various traits. to test this prediction, we used a laboratory model of vertebrate adaptive radiation to investigate the genetic basis of the response to selection for predatory behavior and compare it with evolution of aerobic capacity reported in an earlier work. after 13 generations of selection, the proportion ... | 2016 | 27401229 |
| evolutionary conflict between maternal and paternal interests: integration with evolutionary endocrinology. | conflict between mates, as well as conflict between parents and offspring are due to divergent evolutionary interests of the interacting individuals. hormone systems provide genetically based proximate mechanisms for mediating phenotypic adaptation and maladaptation characteristic of evolutionary conflict between individuals. testosterone (t) is among the most commonly studied hormones in evolutionary biology, and as such, its role in shaping sexually dimorphic behaviors and physiology is relati ... | 2016 | 27400975 |
| experimental evolution on a wild mammal species results in modifications of gut microbial communities. | comparative studies have shown that diet, life history, and phylogeny interact to determine microbial community structure across mammalian hosts. however, these studies are often confounded by numerous factors. selection experiments offer unique opportunities to validate conclusions and test hypotheses generated by comparative studies. we used a replicated, 15-generation selection experiment on bank voles (myodes glareolus) that have been selected for high swim-induced aerobic metabolism, predat ... | 2016 | 27199960 |
| are aryl hydrocarbon receptor and g-protein-coupled receptor 30 involved in the regulation of seasonal testis activity in photosensitive rodent-the bank vole (myodes glareolus)? | within the reproductive system both aryl hydrocarbon receptor (ahr) and g-protein-coupled receptor 30 (gpr30) contribute to estrogen signaling and controlling of reproductive physiology. the specific question is whether and how ahr and gpr30 are involved in regulation of testis function in seasonally breeding rodents. bank vole testes were obtained from animals reared under 18 hours light:6 hours dark (ld) and 6 hours light:18 hours dark (sd) conditions. aryl hydrocarbon receptor and gpr30 expre ... | 2016 | 27004452 |
| population sex-ratio affecting behavior and physiology of overwintering bank voles (myodes glareolus). | many boreal rodents are territorial during the breeding season but during winter become social and aggregate for more energy efficient thermoregulation. communal winter nesting and social interactions are considered to play an important role for the winter survival of these species, yet the topic is relatively little explored. females are suggested to be the initiators of winter aggregations and sometimes reported to survive better than males. this could be due to the higher social tolerance obs ... | 2016 | 26976741 |
| the effect of chlorpyrifos on thermogenic capacity of bank voles selected for increased aerobic exercise metabolism. | agro-chemicals potentially cause adverse effects in non-target organisms. the rate of animal energy metabolism can influence their susceptibility to pesticides by influencing food consumption, biotransformation and elimination rates of toxicants. we used experimental evolution to study the effects of inherent differences in energy metabolism rate and exposure to the organophosphate insecticide, chlorpyrifos (cpf) on thermogenic capacity in a wild rodent, the bank vole (myodes = clethrionomys gla ... | 2016 | 26878110 |
| gerstmann-sträussler-scheinker disease subtypes efficiently transmit in bank voles as genuine prion diseases. | gerstmann-sträussler-scheinker disease (gss) is an inherited neurodegenerative disorder associated with mutations in the prion protein gene and accumulation of misfolded prp with protease-resistant fragments (prp(res)) of 6-8 kda. with the exception of a few gss cases characterized by co-accumulation of prp(res) of 21 kda, efforts to transmit gss to rodents have been unsuccessful. as a result, gss subtypes exclusively associated with 6-8 kda prp(res) have often been considered as non-transmissib ... | 2016 | 26841849 |
| proteome dynamics: tissue variation in the kinetics of proteostasis in intact animals. | understanding the role of protein turnover in the maintenance of proteostasis requires accurate measurements of the rates of replacement of proteins in complex systems, such as intact animals. moreover, any investigation of allometric scaling of protein turnover is likely to include species for which fully annotated proteomes are not available. we have used dietary administration of stable isotope labeled lysine to assess protein turnover rates for proteins from four tissues in the bank vole,myo ... | 2016 | 26839000 |
| fitness costs of increased cataract frequency and cumulative radiation dose in natural mammalian populations from chernobyl. | a cataract is a clouding of the lens that reduces light transmission to the retina, and it decreases the visual acuity of the bearer. the prevalence of cataracts in natural populations of mammals, and their potential ecological significance, is poorly known. cataracts have been reported to arise from high levels of oxidative stress and a major cause of oxidative stress is ionizing radiation. we investigated whether elevated frequencies of cataracts are found in eyes of bank voles myodes glareolu ... | 2016 | 26814168 |
| limits to sustained energy intake. xxiii. does heat dissipation capacity limit the energy budget of lactating bank voles? | understanding factors limiting sustained metabolic rate (susmr) is a central issue in ecological physiology. according to the heat dissipation limit (hdl) theory, the susmr at peak lactation is constrained by the maternal capacity to dissipate body heat. to test that theory, we shaved lactating bank voles (myodes glareolus) to experimentally elevate their capacity for heat dissipation. the voles were sampled from lines selected for high aerobic exercise metabolism (a; characterized also by incre ... | 2016 | 26747907 |
| hindlimb muscle fibre size and glycogen stores in bank voles with increased aerobic exercise metabolism. | to test hypotheses concerning physiological factors limiting the rate of aerobic exercise metabolism, we used a unique experimental evolution model: lines of bank voles selected for high swim-induced aerobic metabolism (a) and unselected, control lines (c). we investigated putative adaptations that result in the increased performance of the hindlimb muscle (gastrocnemius joined with plantaris). the body mass-adjusted muscle mass was higher in a-lines (0.093 g) than in c-lines (0.083 g; p=0.01). ... | 2016 | 26685167 |
| the complete mitochondrial genome of the bank vole clethrionomys glareolus (rodentia: arvicolinae). | we present the first complete sequence of the bank vole (clethrionomys glareolus) mitochondrial genome (genbank accession no. kf918859). the bank vole mitogenome is 16,353 base pairs long and shows the gene content, genome architecture and gene strand asymmetry typical for mammals. the sequence provides an important new genomic resource for the bank vole, which is a popular study species in ecological and evolutionary research. | 2016 | 24438307 |
| epidemiological dynamics of nephropathia epidemica in the republic of tatarstan, russia, during the period of 1997-2013. | this report summarizes epidemiological data on nephropathia epidemica (ne) in the republic of tatarstan, russia. ne cases identified in the period 1997-2013 were investigated in parallel with the hantavirus antigen prevalence in small rodents in the study area. a total of 13 930 ne cases were documented in all but one district of tatarstan, with most cases located in the central and southeastern districts. the ne annual incidence rate exhibited a cyclical pattern, with the highest numbers of cas ... | 2016 | 26160776 |
| [biological effects in natural populations of small rodents in radiation-polluted territories. dynamics of chromosome aberration frequency in a number of generations of european bank vole (clethrionomys glareolus, schreber)]. | the dynamics of chromosome aberration frequency in bone marrow cells of many generations (14) of bank vole living in the radioactive trace of the chernobyl catastrophe (1986-1992) has been analysed. the study revealed that the chromosome aberration frequency in voles in the areas with radio-contamination density 220 and 1526 kbq/m2 (for 137cs) significantly exceeds the control level 3-7 times over the whole period under investigation. the dynamics of the frequency of structural chromosome injuri ... | 2016 | 9876498 |

| [parental care and testosterone in males of the bank vole (myodes glareolus): sensitization and androgenic stimulation of parental behavior]. | the relationship between parental responsiveness of bank vole males and their body weight, testes mass, and plasma and gonadal testosterone levels were examined. two groups of voles were studied: group i consisted of 14 breeding pairs where females gave birth to young within a month after formation of pairs, and group ii represented 13 pairs without offspring and signs of pregnancy in females. males in group i, unlike those in group ii, had contact with pups before the tests on parental responsi ... | 2016 | 23662470 |
| [the effect of a caudal hippocampus lesion on learning in a morris water maze in bank voles (clethrionomys glareolus)]. | a bilateral cytotoxic lesion of the caudal hippocampus (about 1/3 of the whole hippocampus, which is insufficiently studied) influences learning of bank voles (clethrionomys glareolus) in the morris water maze. this effect has been estimated in this paper. a version of the test intended to measure long-term spatial memory was used. the lesion was shown to exert an influence on the learning dynamics by slowing it down, as well as to reduce the accuracy of platform location memorizing at early sta ... | 2016 | 23789425 |
| [evaluation of abundance of residents and immigration by irretrievable requisitioning of the bank vole (myodes glareolus schreber, 1780)]. | the activity of average statistical species was approximated by normal distribution. this is provided by calculation of the part of resident animals without repeated hatching, i.e., the edge effect. residence beyond the space covering 99% of species activity was considered as nonresidence. the appearance of nonresidence in general can be considered as "excursions" and "resettlement." the experiments on requisitioning of small settled animals from a preliminary marked site were carried out. it wa ... | 2016 | 22292295 |
| [structure of the bank vole (myodes glareolus) population cycles in the center and periphery of its distribution area]. | the results of long-term studies of two bank vole (myodes glareolus) populations in stationary sites in the central part and periphery of its distribution area are described. four phases of a multiannual population cycle and two of its structural parts have been detected for both populations. the first part of the cycle is "determined", with the "peak" phase passing into a "depression" (population collapse). this transition is mainly "determined" by intrapopulation processes and is weakly depend ... | 2016 | 22292294 |
| [blood system peculiarities in the bank vole (clethrionomys glareolus) under chronic environmental pollution]. | the parameters of peripheral blood and hemopoietic organs in mature and immature bank voles inhabiting a chemically polluted area were studied. variability of the blood system parameters depending on the level of toxic load and the animals' reproductive status was determined. alteration of the cell composition of erythrocytes and leucocytes, the structure of erythrocytes, and the hemoglobin fractions and leucocyte functions describe the adaptive response to the factors of a changed environment m ... | 2016 | 22117428 |
| [annual variation in hematological indices in a fluctuating population of bank vole (clethrionomys glareolus)]. | the quantitative and structural hematological indices were studied in bank vole in different reproductive states (overwintered individuals, mature underyearlings, and immature underyearlings) in different years corresponding to different phases of the population cycle. the annual changes in certain hematological indices have been revealed for each reproductive state irrespective of the population cycle phase. | 2016 | 19768970 |
| [seasonal variation in hematological indices in bank vole (clethrionomys glareolus) in different reproductive states]. | hematological and hematopoietic indices were studied in various seasons in bank vole in different reproductive states. the seasonal variation in the indices demonstrated patterns typical of each state and reflecting the adaptive response to changed habitat conditions. | 2016 | 17352196 |
| [biological effects in natural populations of small rodents in radiation contaminated areas. the frequency of bone marrow polyploid cells of bank voles in different years following chernobyl accident]. | on the basis of the metaphase analysis results, the peculiarities of dynamics of the genome mutation frequency (polyploid cells) were studied in bone marrow of bank voles inhabiting the areas with different radiocontamination level due to the chernobyl accident (8-1526 kbq/m2 for 137cs) in 1986-1991. unexpectedly high frequencies of polypoid cells exceeding the pre-accidental level by a factor of 10(1)-10(3) were recorded in all populations studied. relationship between the frequency of the para ... | 2016 | 10689427 |
| [the variability of the biochemical status of populations of the bank vole (clethrionomys glareolus) subjected to the chronic action of ionizing radiation in relation to the time of their inhabiting radionuclide-contaminated areas]. | the existence of a population of bank voles in the course of long time (50-60 years) in conditions of chronic ionizing radiation at low doses, promoted adaptation of this populations of rodents to the action of this factor. as opposed to, in a population of bank voles, living radionuclide-contaminated areas during 8-years after the chernobyl accident, adaptation was not observed. | 2016 | 9244535 |
| [the effect of small radiation doses on biological changes in population groupings of murine rodents]. | the influence of low doses of radiation on the biological changes in the population groupings of rodents is traced. correlative dependence between the factors of accumulation of 137cs by animals in contact with the forest litter and vital functions: intensity of reproduction, death of young animals (sad) and size was found at the example of clethrionomys glareolus schreb. however, it is necessary to make amendments to the age structure of the grouping under analysis to use the mentioned above te ... | 2016 | 9244516 |
| rickettsia spp. in small mammals and their parasitizing ectoparasites from saxony, germany. | rickettsiae are emerging pathogens causing various types of spotted fever and typhus and are mostly transmitted by arthropods to humans and animals. in order to investigate the distribution of rickettsiae of the spotted fever group (sfg) in small mammals as potential reservoirs and in fleas and ticks from these animals as potential vectors, a total of 91 small mammals (seven species) were captured and their ectoparasites were collected at seven sites around leipzig, saxony, germany, in 2010 and ... | 2016 | 31014532 |
| a dopamine and noradrenaline reuptake inhibitor (bupropion) does not alter exercise performance of bank voles. | physical performance is determined both by biophysical and physiological limitations and behavioral characteristic, specifically motivation. we applied an experimental evolution approach combined with pharmacological manipulation to test the hypothesis that evolution of increased aerobic exercise performance can be triggered by evolution of motivation to undertake physical activity. we used a unique model system: bank voles from a lines, selected for high swim-induced aerobic metabolism (vo2swim ... | 2016 | 29491918 |
| parasite community dynamics in an invasive vole - from focal introduction to wave front. | multiple parasite species simultaneously infecting a host can interact with one another, which has the potential to influence host-parasite interactions. invasive species typically lose members of their parasite community during the invasion process. not only do the founding population escape their parasites, but the rapid range expansion of invaders once in the invaded range can lead to additional stochastic loss of parasites. as such, parasite community dynamics may change along an invasion gr ... | 2017 | 30951575 |

| state-dependent foraging: lactating voles adjust their foraging behavior according to the presence of a potential nest predator and season. | parental care often produces a trade-off between meeting nutritional demands of offspring and the duties of offspring protection, especially in altricial species. parents have to leave their young unattended for foraging trips, during which nestlings are exposed to predators. we investigated how rodent mothers of altricial young respond to risk of nest predation in their foraging decisions. we studied foraging behavior of lactating bank voles (myodes glareolus) exposed to a nest predator, the co ... | 2017 | 25926712 |
| excretion and measurement of corticosterone and testosterone metabolites in bank voles (myodes glareolus). | the bank vole is a commonly used model species in behavioral and ecophysiological studies. thus, presenting a validated method for noninvasive monitoring of corticosterone and testosterone secretion is of high relevance. here, we evaluated the effect of time of day and an acth challenge test on measured fecal corticosterone (fcm) and testosterone (ftm) metabolites in both sexes. furthermore, we performed radiometabolism experiments for both steroids and sexes to study metabolism and excretion of ... | 2017 | 27815157 |
| de novo transcriptome assembly facilitates characterisation of fast-evolving gene families, mhc class i in the bank vole (myodes glareolus). | the major histocompatibility complex (mhc) plays a central role in the adaptive immune response and is the most polymorphic gene family in vertebrates. although high-throughput sequencing has increasingly been used for genotyping families of co-amplifying mhc genes, its potential to facilitate early steps in the characterisation of mhc variation in nonmodel organism has not been fully explored. in this study we evaluated the usefulness of de novo transcriptome assembly in characterisation of mhc ... | 2017 | 27782121 |
| the effect of aluminum exposure on reproductive ability in the bank vole (myodes glareolus). | human impact on the environment is steadily increasing the amounts of aluminum in the ecosystems. this element accumulates in plants and water, potentially exposing herbivores to its harmful effect. in heavily polluted sites, a decrease in the density of small rodent populations has been observed. this decline may be caused by many factors, including decreased fertility. the aim of the presented research was to determine how aluminum, administered at concentrations similar to those recorded in i ... | 2017 | 27687699 |
| a shift in the thermoregulatory curve as a result of selection for high activity-related aerobic metabolism. | according to the "aerobic capacity model," endothermy in birds and mammals evolved as a result of natural selection favoring increased persistent locomotor activity, fuelled by aerobic metabolism. however, this also increased energy expenditure even during rest, with the lowest metabolic rates occurring in the thermoneutral zone (tnz) and increasing at ambient temperatures (ta) below and above this range, depicted by the thermoregulatory curve. in our experimental evolution system, four lines of ... | 2017 | 29326604 |
| experimental cowpox virus (cpxv) infections of bank voles: exceptional clinical resistance and variable reservoir competence. | cowpox virus (cpxv) is a zoonotic virus and endemic in wild rodent populations in eurasia. serological surveys in europe have reported high prevalence in different vole and mouse species. here, we report on experimental cpxv infections of bank voles (myodes glareolus) from different evolutionary lineages with a spectrum of cpxv strains. all bank voles, independently of lineage, sex and age, were resistant to clinical signs following cpxv inoculation, and no virus shedding was detected in nasal o ... | 2017 | 29257111 |
| variation of metallothionein i and ii gene expression in the bank vole (clethrionomys glareolus) under environmental zinc and cadmium exposure. | the main idea of the study was to assess how environmental metal pollution activates defence responses at transcription levels in the tissues of bank voles (clethrionomys glareolus). for this purpose, the metallothioneine (mt) genes expression (a well known biomarker of exposure and response to various metals) was measured. the real-time pcr method was used for relative quantification of metallothionein i and metallothionein ii expressions in the livers, kidneys and testes of bank voles from six ... | 2017 | 29248947 |
| stabilizing selection on microsatellite allele length at arginine vasopressin 1a receptor and oxytocin receptor loci. | the loci arginine vasopressin receptor 1a (avpr1a) and oxytocin receptor (oxtr) have evolutionarily conserved roles in vertebrate social and sexual behaviour. allelic variation at a microsatellite locus in the 5' regulatory region of these genes is associated with fitness in the bank vole myodes glareolus given the low frequency of long and short alleles at these microsatellite loci in wild bank voles, we used breeding trials to determine whether selection acts against long and short alleles. fe ... | 2017 | 29237850 |
| atypical creutzfeldt-jakob disease with prp-amyloid plaques in white matter: molecular characterization and transmission to bank voles show the m1 strain signature. | amyloid plaques formed by abnormal prion protein (prpsc) aggregates occur with low frequency in creutzfeldt-jakob disease, but represent a pathological hallmark of three relatively rare disease histotypes, namely variant cjd, sporadic cjdmv2k (methionine/valine at prnp codon 129, prpsc type 2 and kuru-type amyloid plaques) and iatrogenic cjdmmik (mm at codon 129, prpsc of intermediate type and kuru plaques). according to recent studies, however, prp-amyloid plaques involving the subcortical and ... | 2017 | 29169405 |
| elevated mitochondrial genome variation after 50 generations of radiation exposure in a wild rodent. | currently, the effects of chronic, continuous low dose environmental irradiation on the mitochondrial genome of resident small mammals are unknown. using the bank vole (myodes glareolus) as a model system, we tested the hypothesis that approximately 50 generations of exposure to the chernobyl environment has significantly altered genetic diversity of the mitochondrial genome. using deep sequencing, we compared mitochondrial genomes from 131 individuals from reference sites with radioactive conta ... | 2017 | 29151870 |
| genetic characterization of bank vole virus (bavv), a new paramyxovirus isolated from kidneys of bank voles in russia. | a genome of bank vole virus (bavv), isolated from kidney tissues of bank voles (myodes glareolus) in russia in 1973, was sequenced. the genomic organization of bavv (3'-n-p/v/c-m-f-g-l-5', 16,992 nt in length; genbank accession number mf943130) is most similar to that of mossman virus (mov) and nariva virus (narpv), two ungrouped paramyxoviruses isolated from rodents in australia and trinidad, respectively. the proteins of bavv have the highest level of sequence identity (ranging from 23-28% for ... | 2017 | 29129019 |
| the molecular identification of calodium hepaticum in the wild brown rat (rattus norvegicus) in poland. | calodium hepaticum is a parasitic nematode found primarily in rodents but known to infect numerous other mammal species, and causing in humans the hepatic calodiasis. herein, we present the first finding of c. hepaticum in rattus norvegicus in poland. in this study, we have used the combined pepsin-hcl digestion and molecular techniques to detect c. hepaticum infection in the liver. the results confirm the usefulness of molecular approaches for investigating the biology and epidemiology of c. he ... | 2017 | 29035861 |
| soluble polymorphic bank vole prion proteins induced by co-expression of quiescin sulfhydryl oxidase in e. coli and their aggregation behaviors. | the infectious prion protein (prpsc or prion) is derived from its cellular form (prpc) through a conformational transition in animal and human prion diseases. studies have shown that the interspecies conversion of prpc to prpsc is largely swayed by species barriers, which is mainly deciphered by the sequence and conformation of the proteins among species. however, the bank vole prpc (bvprp) is highly susceptible to prpsc from different species. transgenic mice expressing bvprp with the polymorph ... | 2017 | 28978309 |
| asparagine and glutamine ladders promote cross-species prion conversion. | prion transmission between species is governed in part by primary sequence similarity between the infectious prion aggregate, prpsc, and the cellular prion protein of the host, prpc a puzzling feature of prion formation is that certain prpc sequences, such as that of bank vole, can be converted by a remarkably broad array of different mammalian prions, whereas others, such as rabbit, show robust resistance to cross-species prion conversion. to examine the structural determinants that confer susc ... | 2017 | 28931606 |
| glareosin: a novel sexually dimorphic urinary lipocalin in the bank vole, myodes glareolus. | the urine of bank voles (myodes glareolus) contains substantial quantities of a small protein that is expressed at much higher levels in males than females, and at higher levels in males in the breeding season. this protein was purified and completely sequenced at the protein level by mass spectrometry. leucine/isoleucine ambiguity was completely resolved by metabolic labelling, monitoring the incorporation of dietary deuterated leucine into specific sites in the protein. the predicted mass of t ... | 2017 | 28878040 |
| comparative stylostome ultrastructure of hirsutiella zachvatkini (trombiculidae) and trombidium holosericeum (trombidiidae) larvae. | stylostomes (feeding tubes) of hirsutiella zachvatkini (schluger) (trombiculidae), feeding on bank voles [myodes glareolus (schreber)], and of trombidium holosericeum (l.) (trombidiidae), feeding on larvae of stenodemini sp. (heteroptera, miridae), were studied by tem methods and on semi-thin sections. the stylostome of h. zachvatkini is a homogeneous structure of low electron density and without strict margins. it extends within the concave host epidermis, undergoing hyperplasia and hyperkerato ... | 2017 | 28852943 |
| does signaling of estrogen-related receptors affect structure and function of bank vole leydig cells? | to get a deeper insight into the function of estrogen-related receptors (errs) and dissect underlying mechanism in leydig cells, errs (type α, β and γ) were blocked or activated in testes of adult bank voles (myodes glareolus) which show seasonal changes in the intratesticular sex hormones level. both actively reproducing animals (long day conditions; ld) and those with regression of the reproductive system (short day conditions; sd) received intraperitoneal injections of selective errα antagoni ... | 2017 | 28820402 |
| mechanical constraint from growing jaw facilitates mammalian dental diversity. | much of the basic information about individual organ development comes from studies using model species. whereas conservation of gene regulatory networks across higher taxa supports generalizations made from a limited number of species, generality of mechanistic inferences remains to be tested in tissue culture systems. here, using mammalian tooth explants cultured in isolation, we investigate self-regulation of patterning by comparing developing molars of the mouse, the model species of mammali ... | 2017 | 28808032 |
| age-related changes of physiological performance and survivorship of bank voles selected for high aerobic capacity. | variation in lifespans is an intriguing phenomenon, but how metabolic rate influence this variation remains unclear. high aerobic capacity can result in health benefits, but also in increased oxidative damage and accelerated ageing. we tested these contradictory predictions using bank voles (myodes=clethrionomys glareolus) from lines selected for high swim-induced aerobic metabolism (a), which had about 50% higher maximum metabolic rate and a higher basal and routine metabolic rates, than those ... | 2017 | 28803134 |
| the bruce effect revisited: is pregnancy termination in female rodents an adaptation to ensure breeding success after male turnover in low densities? | pregnancy termination after encountering a strange male, the bruce effect, is regarded as a counterstrategy of female mammals towards anticipated infanticide. while confirmed in caged rodent pairs, no verification for the bruce effect existed from experimental field populations of small rodents. we suggest that the effect may be adaptive for breeding rodent females only under specific conditions related to populations with cyclically fluctuating densities. we investigated the occurrence of delay ... | 2017 | 28791488 |
| temporal dynamics of the tick ixodes ricinus in northern europe: epidemiological implications. | tick-borne pathogens pose an increasing threat to human and veterinary health across the northern hemisphere. while the seasonal activity of ticks is largely determined by climatic conditions, host-population dynamics are also likely to affect tick abundance. consequently, abundance fluctuations of rodents in northern europe are expected to be translated into tick dynamics, and can hence potentially affect the circulation of tick-borne pathogens. we quantified and explained the temporal dynamics ... | 2017 | 28359294 |
| balancing selection maintains polymorphisms at neurogenetic loci in field experiments. | most variation in behavior has a genetic basis, but the processes determining the level of diversity at behavioral loci are largely unknown for natural populations. expression of arginine vasopressin receptor 1a (avpr1a) and oxytocin receptor (oxtr) in specific regions of the brain regulates diverse social and reproductive behaviors in mammals, including humans. that these genes have important fitness consequences and that natural populations contain extensive diversity at these loci implies the ... | 2017 | 28325880 |
| mercury in soil, earthworms and organs of voles myodes glareolus and shrew sorex araneus in the vicinity of an industrial complex in northwest russia (cherepovets). | the characteristic properties of uptake and distribution of mercury in terrestrial ecosystems have received much lesser attention compared to aquatic particularly in russia. terrestrial ecosystems adjacent to large industrial manufactures-potential sources of mercury inflow into the environment frequently remain unstudied. this is the first report on mercury (hg) levels in the basic elements of terrestrial ecosystems situated close to a large metallurgical complex.mean values of mercury concentr ... | 2017 | 28197948 |
| surviving winter: food, but not habitat structure, prevents crashes in cyclic vole populations. | vole population cycles are a major force driving boreal ecosystem dynamics in northwestern eurasia. however, our understanding of the impact of winter on these cycles is increasingly uncertain, especially because climate change is affecting snow predictability, quality, and abundance. we examined the role of winter weather and snow conditions, the lack of suitable habitat structure during freeze-thaw periods, and the lack of sufficient food as potential causes for winter population crashes. we l ... | 2017 | 28070280 |
| behavioural responses of ixodes ricinus nymphs to carbon dioxide and rodent odour. | many haematophagous ectoparasites use carbon dioxide (co2 ) and host odour to detect and locate their hosts. the tick ixodes ricinus (linnaeus) (ixodida: ixodidae) walks only small distances and quests in vegetation until it encounters a host. the differential effects of co2 and host odour on the host-finding behaviour of i. ricinus have, however, never been clarified and hence represent the subject of this study. the effects of co2 and odour from bank voles on the activation and attraction of i ... | 2017 | 27966215 |
| cryptosporidium infecting wild cricetid rodents from the subfamilies arvicolinae and neotominae. | we undertook a study on cryptosporidium spp. in wild cricetid rodents. fecal samples were collected from meadow voles (microtus pennsylvanicus), southern red-backed voles (myodes gapperi), woodland voles (microtus pinetorum), muskrats (ondatra zibethicus) and peromyscus spp. mice in north america, and from bank voles (myodes glareolus) and common voles (microtus arvalis) in europe. isolates were characterized by sequence and phylogenetic analyses of the small subunit ribosomal rna (ssu) and acti ... | 2017 | 28870264 |

| seasonal shift of diet in bank voles explains trophic fate of anthropogenic osmium? | diet shifts are common in mammals and birds, but little is known about how such shifts along the food web affect contaminant exposure. voles are staple food for many mammalian and avian predators. there is therefore a risk of transfer of contaminants accumulated in voles within the food chain. osmium is one of the rarest earth elements with osmium tetroxide (oso4) as the most toxic vapor-phase airborne contaminant. anthropogenic oso4 accumulates in fruticose lichens that are important winter foo ... | 2017 | 29079088 |
| long-term population patterns of rodents and associated damage in german forestry. | several rodent species can damage forest trees, especially at young tree age in afforestation. population outbreaks of field voles (microtus agrestis l.) and bank voles (myodes glareolus schreber) in particular can cause losses. | 2017 | 27233231 |
| diversity and prevalence of bartonella species in small mammals from slovakia, central europe. | wild-living rodents are important hosts for zoonotic pathogens. bartonella infections are widespread in rodents; however, in slovakia, knowledge on the prevalence of these bacteria in small mammals is limited. we investigated the prevalence and diversity of bartonella species in the spleens of 640 rodents of six species (apodemus flavicollis, apodemus sylvaticus, myodes glareolus, microtus arvalis, microtus subterraneus, and micromys minutus) and in the european mole (talpa europaea) from three ... | 2017 | 28975409 |
| effects of strain and species on the septo-temporal distribution of adult neurogenesis in rodents. | the functional septo-temporal (dorso-ventral) differentiation of the hippocampus is accompanied by gradients of adult hippocampal neurogenesis (ahn) in laboratory rodents. an extensive septal ahn in laboratory mice suggests an emphasis on a relation of ahn to tasks that also depend on the septal hippocampus. domestication experiments indicate that ahn dynamics along the longitudinal axis are subject to selective pressure, questioning if the septal emphasis of ahn in laboratory mice is a rule app ... | 2017 | 29311796 |
| microtus arvalis and arvicola scherman: key players in the echinococcus multilocularis life cycle. | a broad range of rodent species are described as potential intermediate hosts for echinococcus multilocularis, a wide-spread zoonotic cestode causing alveolar echinococcosis. however, little is known about the relative contribution of these species for parasite reproduction and the maintenance of its life cycle. in a comparative study in a high endemic region in zurich, switzerland, we investigated prevalence rates and fertility of e. multilocularis in the most abundant vole species as well as t ... | 2017 | 29326950 |
| spotted fever rickettsiae in wild-living rodents from south-western poland. | rickettsiae are obligate intracellular alpha-proteobacteria. they are transmitted via arthropod vectors, which transmit the bacteria between animals and occasionally to humans. so far, much research has been conducted to indicate reservoir hosts for these microorganisms, but our knowledge is still non-exhaustive. therefore, this survey was undertaken to investigate the presence of rickettsia spp. in wild-living small rodents from south-western poland. | 2017 | 28874204 |
| bank vole immunoheterogeneity may limit nephropatia epidemica emergence in a french non-endemic region. | ecoevolutionary processes affecting hosts, vectors and pathogens are important drivers of zoonotic disease emergence. in this study, we focused on nephropathia epidemica (ne), which is caused by puumala hantavirus (puuv) whose natural reservoir is the bank vole, myodes glareolus. we questioned the possibility of ne emergence in a french region that is considered to be ne-free but that is adjacent to a ne-endemic region. we first confirmed the epidemiology of these two regions and we demonstrated ... | 2017 | 28931451 |
| increased autumn rainfall disrupts predator-prey interactions in fragmented boreal forests. | there is a pressing need to understand how changing climate interacts with land-use change to affect predator-prey interactions in fragmented landscapes. this is particularly true in boreal ecosystems facing fast climate change and intensification in forestry practices. here, we investigated the relative influence of autumn climate and habitat quality on the food-storing behaviour of a generalist predator, the pygmy owl, using a unique data set of 15 850 prey items recorded in western finland ov ... | 2017 | 27371812 |
| ecological factors influencing small mammal infection by anaplasma phagocytophilum and borrelia burgdorferi s.l. in agricultural and forest landscapes. | small mammals are key components of numerous tick-borne disease systems, as hosts for immature ticks and pathogen reservoirs. to study the factors influencing tick-borne infection in small mammals, we trapped small mammals and collected questing ticks in spring and autumn in 2012 and 2013 at 24 sites in a 10x15 km rural landscapes (brittany, france). tissue samples were screened by real-time pcr for anaplasma phagocytophilum and borrelia burgdorferi sensu lato. of the two dominant small mammal s ... | 2017 | 28799685 |
| prevalence and genetic variability of anaplasma phagocytophilum in wild rodents from the italian alps. | human granulocytic anaplasmosis is a zoonotic bacterial disease with increasing relevance for public health in europe. the understanding of its sylvatic cycle and identification of competent reservoir hosts are essential for improving disease risk models and planning preventative measures. | 2017 | 28615038 |
| low prevalence of zoonotic babesia in small mammals and ixodes ricinus in brittany, france. | in order to evaluate the zoonotic risk due to babesia spp., especially b. microti, we investigated their presence in 597 individuals of five small mammal species and in 2620 questing nymphs of ixodes ricinus in rural landscapes of western france (brittany). small mammals (rodents and shrews) are indeed suspected to be reservoir hosts for b. microti, and the tick i. ricinus is the vector of the three main zoonotic species in europe, i.e. b. divergens, b. venatorum and b. microti. only one bank vo ... | 2017 | 28392045 |
| rodents as a reservoir of infection caused by multiple zoonotic species/genotypes of c. parvum, c. hominis, c. suis, c. scrofarum, and the first evidence of c. muskrat genotypes i and ii of rodents in europe. | cryptosporidium spp. is an important causative agent of intestinal parasitoses-induced diarrhoea in humans and animals worldwide. rodents (small mammals), the main reservoir of infections, are globally expanded and overpopulated, which increases the risk of transfer of human and zoonotic pathogens from the genus cryptosporidium. in this study, cryptosporidium was detected in wild immunocompetent asymptomatic small mammals. altogether 262 fecal samples were collected from five areas in eastern sl ... | 2017 | 28433573 |
| dampening of population cycles in voles affects small mammal community structure, decreases diversity, and increases prevalence of a zoonotic disease. | long-term decline and depression of density in cyclic small rodents is a recent widespread phenomenon. these observed changes at the population level might have cascading effects at the ecosystem level. here, we assessed relationships between changing boreal landscapes and biodiversity changes of small mammal communities. we also inferred potential effects of observed community changes for increased transmission risk of puumala virus (puuv) spread, causing the zoonotic disease nephropatica epide ... | 2017 | 28770071 |
| spatial prediction and validation of zoonotic hazard through micro-habitat properties: where does puumala hantavirus hole - up? | to predict the risk of infectious diseases originating in wildlife, it is important to identify habitats that allow the co-occurrence of pathogens and their hosts. puumala hantavirus (puuv) is a directly-transmitted rna virus that causes hemorrhagic fever in humans, and is carried and transmitted by the bank vole (myodes glareolus). in northern sweden, bank voles undergo 3-4 year population cycles, during which their spatial distribution varies greatly. | 2017 | 28747170 |
